Title
Multiple Out-of-Bounds Reads in Frame Processing
Summary
SOEM version 2.0.0 and earlier contains multiple vulnerabilities in frame processing where a malicious device can cause the master to read data outside allocated buffers. The software uses length and offset values from device messages without validating them against buffer sizes. This can cause the master to access invalid memory locations, potentially disclosing sensitive information or causing crashes.

Title
Null Pointer Dereference in Mailbox Error Handling
Summary
SOEM version 2.0.0 and earlier contains a vulnerability where a malicious device can crash the master system. When the software receives an error response, it clears an internal pointer but continues processing. If another message arrives before timeout, the software attempts to use the cleared pointer, causing a crash. An attacker can trigger this with a simple sequence of two messages.

Title
Memory Corruption via FMMU Configuration Table Overflow
Summary
SOEM version 2.0.0 and earlier contains a vulnerability during device configuration where a malicious device can cause memory corruption. The software writes configuration data to a fixed-size array without checking if the array index exceeds its maximum size of EC_MAXFMMU entries. A device presenting more than EC_MAXFMMU configuration blocks can force writes beyond the array boundary, corrupting adjacent memory structures and potentially disrupting subsequent operations.

Title
Buffer Overflow in CoE SDO Upload Multi-Segment Data Transfers
Summary
SOEM version 2.0.0 and earlier contains a vulnerability in multi-segment data transfers where a malicious device can overflow memory buffers. The software checks the total size only once at the beginning, but doesn't track the cumulative size as multiple segments arrive. An attacker can declare a small initial size to pass validation, then send additional segments that exceed the allocated buffer. This allows the attacker to write controlled data beyond buffer boundaries, potentially enabling code execution.

Title
Out-of-Bounds Read via Unchecked Length Values
Summary
SOEM version 2.0.0 and earlier contains vulnerabilities where a malicious device can send messages that cause the master to read data from memory locations beyond the intended buffer. The software uses length values from device responses without validating them against actual buffer sizes. An attacker can exploit this to extract up to 64KB of data from the master's memory.

Title
Memory Corruption via Integer Underflow in Message Length Validation
Summary
SOEM version 2.0.0 and earlier contains vulnerabilities where a malicious device on the network can send specially crafted messages that cause the master to write data outside allocated memory boundaries. The software performs arithmetic on message length values without proper validation, allowing negative or extremely large values to bypass safety checks. This can corrupt memory and potentially allow an attacker to execute arbitrary code on the master system.

Title
Multiple Out-of-Bounds Reads in Frame Processing
Summary
SOEM version 2.0.0 and earlier contains multiple vulnerabilities in frame processing where a malicious device can cause the master to read data outside allocated buffers. The software uses length and offset values from device messages without validating them against buffer sizes. This can cause the master to access invalid memory locations, potentially disclosing sensitive information or causing crashes.

Title
Null Pointer Dereference in Mailbox Error Handling
Summary
SOEM version 2.0.0 and earlier contains a vulnerability where a malicious device can crash the master system. When the software receives an error response, it clears an internal pointer but continues processing. If another message arrives before timeout, the software attempts to use the cleared pointer, causing a crash. An attacker can trigger this with a simple sequence of two messages.

Title
Memory Corruption via FMMU Configuration Table Overflow
Summary
SOEM version 2.0.0 and earlier contains a vulnerability during device configuration where a malicious device can cause memory corruption. The software writes configuration data to a fixed-size array without checking if the array index exceeds its maximum size of EC_MAXFMMU entries. A device presenting more than EC_MAXFMMU configuration blocks can force writes beyond the array boundary, corrupting adjacent memory structures and potentially disrupting subsequent operations.

Title
Buffer Overflow in CoE SDO Upload Multi-Segment Data Transfers
Summary
SOEM version 2.0.0 and earlier contains a vulnerability in multi-segment data transfers where a malicious device can overflow memory buffers. The software checks the total size only once at the beginning, but doesn't track the cumulative size as multiple segments arrive. An attacker can declare a small initial size to pass validation, then send additional segments that exceed the allocated buffer. This allows the attacker to write controlled data beyond buffer boundaries, potentially enabling code execution.
Severity
8.8 (High)

Title
Out-of-Bounds Read via Unchecked Length Values
Summary
SOEM version 2.0.0 and earlier contains vulnerabilities where a malicious device can send messages that cause the master to read data from memory locations beyond the intended buffer. The software uses length values from device responses without validating them against actual buffer sizes. An attacker can exploit this to extract up to 64KB of data from the master's memory.

Title
Memory Corruption via Integer Underflow in Message Length Validation
Summary
SOEM version 2.0.0 and earlier contains vulnerabilities where a malicious device on the network can send specially crafted messages that cause the master to write data outside allocated memory boundaries. The software performs arithmetic on message length values without proper validation, allowing negative or extremely large values to bypass safety checks. This can corrupt memory and potentially allow an attacker to execute arbitrary code on the master system.

8.3 (High)
